Transesterification of Used Cooking Oil Over Alkali Metal (Li, Na, K) Supported Rice Husk Silica as Potential Solid Base Catalyst

Transesterification of Used Cooking Oil Over Alkali Metal (Li, Na, K) Supported Rice Husk Silica as Potential Solid Base Catalyst

Investigation was conducted on three alkali metals (Li, Na, and K) supported by rice husk silica as catalysts for methyl esters production. A simple pseudo-heterogeneous transesterification process of used cooking oil with methanol was conducted to produce methyl esters using calcined alkali metal s...
